摘要

以聚丙烯酸钠(PAANa)和聚n -(2-氨基乙基)-3-氨基丙基三甲氧基硅烷(PAPTMS)为基础的有机-无机亲水性复合材料在加入PAPTMS后，其溶胀性能得到改善。在20%的PAPTMS含量下，观察到非菲克斯型到超级II型肿胀行为的变化。与PAA相比，复合水凝胶的热稳定性和耐热性指数均有所提高。

Effect of Diaminosilane Derivative on Thermal and Swelling Behaviour of Acrylic Acid Based Hydrophilic Composites

Organic-inorganic hydrophilic composites based on sodium polyacrylate (PAANa) and poly-N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (PAPTMS) showed the improved swelling capacity at incorporation of PAPTMS. Changing of non-Fickian to Super case II swelling behaviour is observed at 20 wt % PAPTMS content. Enhancing of thermal stability and heat-resistance index of composite hydrogels compared to PAA is shown.
